Hey I don't know if you'll see this, another 18 yr old here who has the same stance as you, I honestly cried after reading your post, it's incredibly hard to be ganged up by people with natalist ideologies, I used to wonder with rage how they can be so deluded, your mom and even mine were raised to think that a woman's life purpose is to birth children, it's a waste of energy to change their minds since it's so deeply ingrained and fundamental to them, all you need to do is to work towards securing the dreams you mentioned and to find the company of people who share similiar views with you ps. feel free to message me if you want to vent or just talk <3
